Removing test TestScheduleInParallelRunsInDelayOrder.

It should be fine to remove this test since there's no need for ordering of different threads using relative time, and we do not offer ordering guarantees for relative timings across different threads.
Ordering on a single thread is guaranteed and is still tested.

Fix: 237099553
Test: We are just removing a test.
